An atypical Arp2/3 complex is required for Plasmodium DNA segregation and malaria transmission.
Article in Nature microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Plasmodium parasites, the causative agents of malaria, undergo crucial developments within the mosquito vector, initiated by the formation of male and female gametes. Male gametogenesis involves three rapid rounds of mitosis without nuclear or cell division, followed by a single round of DNA segregation and nuclear division during gamete budding. How the cell organizes the segregation of eight genomes from a single octoploid nucleus into eight haploid gametes is currently unknown. Here we discovered an atypical Arp2/3 complex in Plasmodium important for DNA segregation during male gametogenesis. Unlike the canonical Arp2/3 complex found in other eukaryotes, Plasmodium Arp2/3 localizes to endomitotic spindles and interacts with a kinetochore-associated protein. Disruption of Arp2/3 subunits or actin polymerization interferes with kinetochore-spindle association, causes the formation of subhaploid gametes, and blocks transmission. Our work identified an evolutionary divergent Arp2/3 complex in malaria parasites, provides insights into gametogenesis, and reveals potential targets for transmission-blocking interventions.
